Introduction

Congratulations and thank you for purchasing the ELAC IS-AMP340 Amplifier! Since the time we started in 1926, ELAC has always striven to achieve the very best! IS-AMP340 is a 3 channel amplifier with a line output for connecting a subwoofer. The amplifier allows you to connect a center speaker in addition to left and right speakers. A subwoofer line output is included for connecting a powered subwoofer to reproduce deep and rich bass. The center speaker connection is optional, but provides clearer dialogue reproduction.

App-rich Control Flexibility

ELAC’s free iOS and Android app allows users to fully control and set up their system. The app includes innovative features not found on any other products in this class—anywhere.

Auto Blend and Auto EQ

Through the use of the free iOS and Android app the user first selects a high-pass filter, then using the smartphone’s microphone, measures the near-field response of both the main speakers and subwoofer. Our proprietary algorithm then adjusts the low pass filter to obtain optimal blending between the subwoofer and main speakers. Auto EQ minimizes the effects of the rooms acoustics allowing you to hear the sound the designer intended. Please read and follow the instructions in this guide to assist in proper installation, connection and use of your ELAC IS-AMP340 Amplifier.

IS-AMP340 App

IS-AMP340 APP

The IS-AMP340 App is a two-way setup app that connects to the amp via Bluetooth Low Energy. App setup features include: source select, master volume, offset (individual source) volume, source naming, bass/treble, sub volume, balance, Auto Blend, IR Remote learning and screen brightness. The app will open to the Master Volume screen when launched.

MASTER VOLUME

The Master Volume slider sets the amplifier output volume. It affects the output to the speakers and sub (if used) and headphones if connected. When adjusting master volume, the volume level will appear in a bubble on the app screen and on the front panel display. If the volume is adjusted with the IR remote or front panel volume control, the app master volume will adjust automatically in real time.

OFFSET VOLUME

The Offset Volume slider sets the output of each connected source relative to the other sources. This allows adjusting the source levels so when switching from one source to another, one won’t be very loud and another very soft. When adjusting Offset level be sure to use program material that is equal in intensity, volume and dynamics so the settings are made to the relative output of the sources and not the program material itself. Setting the Offset on one source to soft solo harp music and another to pounding electronic dance music will not result in proper settings. The app provides two digital meters to indicate the relative input and output level of each source. Green is good. Amber is OK, but not too much, and Red is bad. The ideal settings have the Output levels set so that no source is in the red and maybe just flickering the amber cell. Also try to set the individual outputs so that no source can get so loud that it can damage the amp, speakers or your ears, even if the amp gets turned all the way up! The Offset levels can only be adjusted using the app…so keep the app away from the kids and friends!

1. Before setting the Offsets, turn the Master Volume down a bit just in case a particular source comes on louder than expected.
2. With all connected sources playing consistent program material, tap through all inputs at the top of the app screen to get a feel for which input are louder and softer.
3. Adjust the Offset for each source until the output from the speakers is consistent across all sources. The settings will be automatically stored in the amp.
